UNITED STATES lie-.TENT OFFICE FREDERICK H. WILLCOX, OF CHICAGO, ILLINOIS, ASSIGNOR 'IO FREYN ENGINEERING COMPANY, 0F CHICAGO, ILLINOIS, A CORPORATION OF MAINE BURNER Application led October 22, 1925.

The present invention relates to burners.

An object of the present invention is to provide a burner .of simple design which will produce a thorough mixture of combustion gas and air.

A further obj ect is to provide a burner suitable for blast furnace and other gas operation which will efiiciently meet the needs of commercial operation Further obj ects will appear as the description proceeds.

Referring to the drawings- Figure '1 is a top plan view of a burner embodying the principles of the present invention, parts being broken away to show the interior construction;

Figure 2 is a view partly in section, said view being taken along the planes indicated by the arrows 2 2 of Figure 1; expressed in other language, Figure 2 is an elevational view looking toward the nozzle of the burner Shown in Figure 1, parts being broken away to show the interior construction;

Figure 3 is a sectional view taken along the plane indicated by the arrows 3 3 of Figure 1; and

Figure 4 is a sectional View taken along the -plane indicated by the arrows 4 4 of Figure 1.

The present invention provides a construc tion in which gas is emitted to a chamber which distributes said gas to various apertures. Air is admitted through apertures in said chamber and impinges against the gas current in a manner to produce a thorough mixture of gas and air, which mixture is more completely accomplished by the expansion of the gas and air mixture before said mixture is emitted from the nozzles, of the burner.

The illustrated embodiment of the present invention includes the casing 10 having the gas inlet port 11. The numeral 12 indicates a conduit of converging conformation for conducting gas to said port 11. Said port 11 leads to the gas chamber 13, access to which may be had by means of the door 14. The gas chamber 13 extends the full width of the casing 10 and is provided along its front side with a plurality of nozzles 1 15, of which six are shown 1n the illustrated embodiment Serial No. 64,126.

of the present invention. Said nozzles are provided by the converging walls 1(3 16, which extend from top to bottom of the cas ing 10.

The numeral 17 indicates an air port through which air is directed to the interior of casing 10 from the air inlet 18. Said air ports 17-17 correspond in number to the gas ports 15 15 and are located in the bottom wall of the casing 10 symmetrically with the inner sides of adjacent walls 1G 16. Positioned to form flaring nozzles 19 19 are the vertical walls 20 20, the adjacent walls 20 20 between said nozzles 19 19 being united at their forward ends to form closures. Said nozzles 19 19 correspond in number and location with nozzles 15 15. Pairs of walls 16 16 are mounted in symmetrical relationship with pairs of walls 20 20, ports 21 21 being provided between each wall 1G and its adjacent wall 20, whereby air from the ports 17-17 may communicate with gas entering through ports 15-15. Said air impinges against the gas current at approximately right angles, producing a thorough mixture, which mixture is furthered by the expansion of the gas as it emerges into the flaring nozzles 19 19.

An important advantage of the present invention is that it adapts itself for different sizes, according to the capacity desired, without sacriice of eiliciency. For example, the structure illustrated in the drawing, which has six nozzles, illustrates a construction taken from practice which is suitable for 360 boiler Il. P. when using blast furnace gas. The number of nozzles may be increased as desired without sacrificing efliciency.

The air and gas supplied to the burner constituting the subject matter of the present invention may be controlled both as to amounts and to ratios by any one of the several coinmercial regulators now on the market.

Though the preferred embodiment of the present invention has been described in detail1 9 it will be clear that many modifications will occur to those skilled in the art. It is intended to cover all such modifications that fall within the scope of the appended claims.

What is claimed is ici Cil

1. A burner comprising a housing provided with a plurality of pairs of walls providing flaring passageways at the forward portion of said housing and having a like nuinber of pairs of walls forming converging passageways leading to the passageway/'s forined by said first-mentioned pairs of walls, said housing having inlet apertures c-oininunieating with the spaces between the walls of said first-mentioned pairs and with the spaces between the walls of said second-mentioned pairs, said housing having an aperture coininunicating with the space in rear of said second-mentioned pairs of walls, said firstmentioned pairs of walls being spaced from said second-mentioned pairs of walls to provide access between said first-mentioned apertures and the space in rear of said second-mentioned pairs of walls.

2. A burner comprising a housing having a plurality of sets of forward walls arranged in cooperative relationship with one another to provide passageways flaring toward the front of said burner, a plurality of sets of rearward walls forming converging passageways leading to said flaring passageways, the space between each two adjacent sets of said forward walls and the corresponding space between the corresponding sets of rearward walls being open to each other and providing an aperture, said forward walls being spaced from said rearward walls to provide access from between said sets of forward and rearward walls to said flaring passageways, a conduit connecting with said apertures and a conduit leading to the rear of said rearward walls.

3. A burner comprising a housing of sul stantially uniform height, said housing being provided at the forward portion thereof with sets of walls arranged in pairs to provide passageways flaring to the forward portion of said burner, sets of rearward walls arranged in converging relationship with each other to provide converging passageways leading to the rear of said flaring passageways, said forward walls beinespaced from said rearward walls, the space between each two adjacent sets of said forward walls and the corresponding space between the corresponding sets of rearward walls being open to each other and providing an aperture, a conduit for delivering fluid to said apertures, and a conduit for conducting fluid to the larger portions of said converging passageways.

A. A burner comprising a housing, said housing being provided at the forward p0rtion thereof with walls arranged in pairs to provide passageways flaring to the forward portion of said burner, rearward walls arranged in pairs in converging relationship with each other to provide converging passageways leading to the rear of said flaring passageways, said forward walls being spaced from said rearward walls, the space between each two adjacent pairs of said iirstmentioned walls and the corresponding space between the corresponding pairs of said rearward walls being open to each other and providing anlaperture, a conduit for delivering fluid to said apertures, and a conduit for conducting fluid to the larger portions of said converging passageways,

5. A burner comprising a housing, said housing being provided with a plurality of pairs of forward walls, each pair forming a flaring passageway, said housing being provided with a plurality of pairs of rearward walls arranged symmetrically with said forward walls, each pair of said rearward walls providing a converging passageway leading to one of said flaring passageways, the space between each two adjacent pairs offorward walls and the corresponding space between the corresponding pairs of rearward walls being open'to each other and providing an aperture, said spaces connecting with the regions between said converging passageways and said flaring passageways, a conduit leading to said apertures, and a conduit yleading t-o the space in rear of said rearward walls.
